Bugs when combat move is before purchase

Many including "World War II Global 1940 Balanced Mod3 with Combat Move First"

Can you describe how to trigger the error? (eg: what sequence of actions will recreate it?)

(2) Move all units out of a capital. Plunder that capital's PUs. It is now possible to spend that money, which is incorrect.
(3) PBF post option is provided before purchase - this is wrong. Should be showing purchases before asking defender decisions.

Instead of this error, what should have happened?

(2) I say don't do the combat in combat movement - create a NonFightingBattle so that it occurs automatically in BattleDelegate.start()
(3) I suggest a special movement phase to allow posting only, and an XML option to prevent posting in the normal phase.

Any additional information that may help

#1184. Probably too hard to fix and not high enough impact. It's already in the notes.
